Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, possibility of GERD (
gastroesophageal reflux disease) is more likely.
GERD is commonly seen in obese people.
GERD is due to laxity of gastroesophageal sphincter. Because of this, the acid of the stomach tends to come up in the
esophagus and cause stomach fullness,
bloating, breathing difficulty etc.
So first of all try to loose weight by dieting and exercise.
Avoid
stress and tension, be relax and calm.
Quit
smoking and alcohol if you have these habits.
Avoid hot and spicy food. Avoid junk food.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
